4J36 (Invar) ka whakamahia ki nga waahi e hiahiatia ana kia mau tonu te ahua nui, penei i nga taputapu tika, nga karaka, nga inenga ngokingoki ruru, nga papa whakaata-a-whakaata, nga maru i roto i nga motuka, me nga mataaratanga antimagnetic. I roto i te rūri whenua, ka mahia te ota tuatahi (te tino tika) te whakatauritenga teitei, ka mahia nga kaimahi Taumata (te rakau taumata)Invar, hei utu mo te rakau, te muka karaihe, me etahi atu konganuku. I whakamahia nga struts invar i etahi piston hei whakawhāiti i te roha wera i roto i o ratou puoto.
4J36 whakamahi oxyacetylene fehokotaki'anga, fehokotaki'anga pewa hiko, fehokotaki'anga me ētahi atu tikanga fehokotaki'anga. I te mea ko te whakarea o te roha me te hanganga matū o te koranu e hono ana me karohia na te mea ka puta he huringa i roto i te hanganga koranu, he pai ake te whakamahi i nga konganuku whakakikorua ki te 0.5% ki te 1.5% o te titanium. whakaiti i te porosity weld me te kapiti.
